Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and apparatus for detecting and controlling a user equipment (UE)-specific search space (USS). Background Art

[0002] In the Release 17 (Rel-17) dynamic spectrum sharing project, research was conducted on the scheduling of the primary cell (PCell) by the secondary cell (SCell). From the perspective of configuration flexibility and network deployment adaptability, it is allowed to configure the user equipment-specific search space (USS) on the SCell that schedules the PCell and on the scheduled PCell. However, considering the complexity of the terminal, the capacity of the Physical Downlink Control Channel (PDCCH), and the ability to detect the USS on the SCell and PCell at the same time, there is currently no clear solution for detecting the downlink control information (DCI) sent in the USS on the SCell used to schedule the PCell and the scheduled PCell.

[0003] In the existing technology, the network side can configure multiple service cells for the terminal in order to increase the data transmission rate and improve the user experience. In the Rel-15 / 16 version of the new radio access technology (New RAT, NR) system, PCell can only be used as a scheduling carrier, that is, it is not allowed to be scheduled by SCell. In version 17 (Rel-17), it is determined to support SCell scheduling of PCell. In addition, USS is allowed to be configured on the scheduled PCell. Although the USS configuration problem has been solved, there are currently different ideas on how to detect the USS on PCell and SCell. How to ensure that the USS on PCell / PSCell and SCell do not appear at the same time, there is no relevant solution.

[0004] In summary, in current networks, USS can only be configured and detected on the scheduling carrier, which restricts the flexibility and adaptability of network deployment. Summary of the Invention

[0105] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings. It should be noted that the order in which the embodiments of the present application are presented only represents the order of the embodiments, and does not represent the advantages or disadvantages of the technical solutions provided by the embodiments.

[0106] In the technical solution provided by the embodiments of the present application, when the network side configures USSs on both the scheduling carrier and the scheduled carrier, the base station dynamically instructs the terminal on which carrier to detect the USS. The scheduling carrier is a carrier used to transmit the physical downlink control channel (PDCCH) that schedules a data channel on another carrier; the scheduled carrier is a carrier that transmits a data channel scheduled by the PDCCH transmitted on another carrier or the current carrier.

[0107] The following is an introduction from different aspects.

[0108] Terminal side:

[0109] The terminal determines which serving cell's USS to monitor by one of the following methods.

[0110] Method 1: Determine the USS on the monitoring scheduling carrier or the scheduled carrier according to the re-farmed dormancy information field.

[0111] The refarming function is to assign new meaning and functionality to existing information fields. The dormancy information field is used to indicate whether the serving cell has entered a dormancy or non-dormancy state and is a defined field in the NR system.

[0112] Through explicit signaling configuration or protocol pre-defined manner, some bits in dormancy are determined to indicate the monitoring state of the USS (ie, monitoring or non-monitoring).

[0113] Explicit signaling (e.g., RRC signaling) is used to configure whether some bits in the dormancy information are used to indicate the monitoring status of the USS. For example, when USS is configured on both the scheduling carrier and the scheduled carrier, a 1-bit indication field is used to indicate whether the information bits corresponding to the scheduling carrier and the scheduled carrier in the dormancy indication information are refarmed.

[0114] For example:

[0115] If the 1-bit dormancy refarming indication information is 0, it indicates no refarming and maintains the function of the current dormancy indication information (specifically indicating whether the terminal needs to monitor the downlink control channel on certain serving cells).

[0116] If the 1-bit dormancy refarming indication information is 1, it indicates that the dormancy field is refarmed, that is, the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is used to indicate the monitoring state of the USS on the corresponding cell, and no longer indicates the dormancy state.

[0117] When the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is 0, USS is not monitored on the corresponding carrier; when the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is 1, USS is monitored on the corresponding carrier.

[0118] Method 2: Determine which carrier to monitor the USS on based on a USS skipping indication sent on a scheduling carrier or a scheduled carrier.

[0119] The DCI carries a 1-bit USS skipping indication to indicate subsequent USS monitoring information on the carrier transmitting the DCI.

[0120] For example, 1 indicates that the USS on the cell is subsequently skipped, and 0 indicates that the USS on the cell is monitored.

[0121] Furthermore, when the USS skipping indication is 1, the terminal does not monitor the USS on the cell within a time window containing W slots. The time window is configured through high-layer signaling.

[0122] The USS skipping indication is carried by downlink control information (DCI) or media access control element (MAC CE).

[0123] Method 3: Determine the USS to monitor on the scheduling carrier or the scheduled carrier according to the search space number of the DCI monitored on the first carrier (scheduling carrier or scheduled carrier).

[0124] For example, the specific steps include:

[0125] Step 1: Determine the first carrier by protocol pre-definition or high-layer signaling (RRC signaling) indication.

[0126] The first carrier is a scheduling carrier or a scheduled carrier.

[0127] Step 2: First, monitor the PDCCH in the USS on the first carrier.

[0128] Step 3: Determine the subsequent USS monitoring behavior based on the search space number corresponding to the monitored PDCCH and the correspondence between the search space number and the USS monitoring situation, for example, including: monitoring the USS on the first carrier and the second carrier (scheduling carrier or scheduled carrier) at the same time, or monitoring the USS only on the first carrier.

[0129] The correspondence between the search space number and the USS monitoring status is configured through RRC signaling.

[0130] Method 4: Determine to monitor the USS on the scheduling carrier or the scheduled carrier according to the USS activation / deactivation indication information sent on the first carrier.

[0131] The first carrier is determined by protocol pre-definition or high-layer signaling (RRC signaling) indication.

[0132] Related signaling is sent on the first carrier to implement activation / de-activation of the USS on the second carrier.

[0133] The relevant signaling indicates whether the USS of the terminal on the second carrier is in an activated state.

[0134] The terminal only monitors the USS in the active state on the second carrier.

[0135] Before receiving activation signaling of the USS on the second carrier on the first carrier, the terminal does not monitor the USS on the second carrier.

[0136] Base station side:

[0137] Corresponding to the terminal side, the base station notifies the terminal of which serving cell's USS to monitor through one of the following methods:

[0138] Method 1: The refarmed dormancy information field is used to instruct the terminal to monitor the USS on the scheduling carrier or the scheduled carrier.

[0139] Method 2: The USS skipping indication sent on the scheduling carrier or the scheduled carrier notifies the terminal on which carrier it needs to monitor the USS.

[0140] Method 3: By monitoring the search space number of the DCI on the first carrier, the terminal is notified to monitor the USS on the scheduling carrier or the scheduled carrier.

[0141] Method 4: Notify the terminal to monitor the USS on the scheduling carrier or the scheduled carrier through USS activation / de-activation indication information sent on the first carrier.

[0142] The specific details of the above method are the same as those described on the terminal side and will not be repeated here.

[0143] Several specific embodiments are described below.

[0144] Example 1:

[0145] Assume that the PCell of the NR UE and the LTE base station are deployed on the same frequency band. In order to avoid CRS interference from the LTE system, the gNB needs to avoid the REs occupied by the LTE CRS when sending the NR PDCCH. In order to ensure the flexibility of network deployment and scheduling, and reduce the probability of PDCCH collision (blocking possibility) on the NR PCell / PSCell, the SCell is allowed to schedule the PCell. In this embodiment, it is assumed that USS is configured on both the scheduling SCell and the scheduled PCell / PSCell. Monitoring the USS on the scheduling carrier and the scheduled carrier at the same time will cause a huge burden on the terminal side. The terminal needs to dynamically switch between the PCell / PSCell and the SCell, that is, it will only monitor the USS on the PCell / PSCell or the SCell.

[0146] In this embodiment, the dormancy indication field carried in DCI format 2-6 or DCI format 0_1 ​​or DCI format 1_1 indicates that the terminal needs to monitor the USS on the PCell / PSCell and / or SCell.

[0147] The terminal first determines which bits in the dormancy field are used to indicate the monitoring status of the USS based on explicit signaling or protocol predefined methods. Specifically, the network side can indicate to the terminal through RRC signaling whether to re-farm some bits in the dormancy indication field carried in DCI format 2-6, DCI format 0_1, or DCI format 1_1. For example, the above function can be implemented through explicit signaling as shown in the following table:

[0148]

[0149] As shown above, the Dormancy Re-farming Enable IE can be used to indicate the refarming of corresponding bits in the dormancy bitmap for the PCell / PSCell and SCell, allowing the corresponding dormancy function to be configured for the PCell / PSCell. Alternatively, it can be used to indicate the refarming of corresponding bits in the dormancy bitmap for the SCell. If the network instructs the refarming of certain bits in the dormancy bitmap, the corresponding N bit is no longer used to indicate the dormancy status of the corresponding cell, but is used to indicate whether to monitor the USS on the corresponding cell.

[0150] For example, when USS is configured on both PCell / PSCell and SCell, a 1-bit indication field is used to indicate whether to refarm the information bits corresponding to the PCell / PSCell and SCell in the dormancy indication information.

[0151] If the 1-bit dormancy recultivation indication information is 0, it indicates no recultivation and the function of the current dormancy indication information is maintained.

[0152] If the 1-bit dormancy refarming indication information is 1, it indicates that the dormancy field is refarmed, that is, the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is used to indicate the monitoring status of the USS on the corresponding cell, and no longer indicates the dormancy state.

[0153] When the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is 0, the USS is not monitored on the corresponding carrier; when the dormancy bit corresponding to the scheduling carrier and / or the scheduled carrier is 1, the USS is monitored on the corresponding carrier. Figure 1 shown.

[0154] As a specific example, assume that the network side configures the refarming dormancy indication field through RRC signaling, and the PCell / PSCell and SCell correspond to the 2 most significant bits (MSB) in the dormancy indication field. In this case, the two bits are used to indicate the monitoring status of the USS on the PCell / PSCell and SCell, respectively. The following table only gives the function of the 2 bits in the dormancy indication field used to indicate the USS monitoring status.

[0155]

[0156] Example 2:

[0157] Assume that the NR UE's PCell and the LTE base station are deployed on the same frequency band. To avoid CRS interference from the LTE system, the gNB must avoid REs occupied by LTE CRS when transmitting the NR PDCCH. To ensure network deployment and scheduling flexibility and reduce PDCCH blockage on the NR PCell / PSCell, the SCell is allowed to schedule the PCell.

[0158] In this embodiment, it is assumed that USSs are configured on both the scheduling SCell and the scheduled PCell / PSCell. Simultaneously monitoring USSs on both the scheduling and scheduled carriers would place a significant burden on the terminal. The terminal would need to dynamically switch between the PCell / PSCell and the SCell, meaning it would only monitor USSs on the PCell / PSCell or the SCell.

[0159] In this embodiment, the network side indicates whether the terminal needs to skip the USS configured on the corresponding carrier by carrying the USS skipping indication in the DCI. The corresponding carrier is the carrier that transmits the DCI carrying the USS skipping indication. The USS skipping indication includes 1 bit of indication information.

[0160] In this embodiment, see Figure 2 When the USS skipping indication is 0, it indicates that the terminal needs to continue monitoring the USS on the cell; when the USS skipping indication is 1, it indicates that the terminal will subsequently skip the USS on the cell. The DCI carrying the USS skipping indication can be a DCI for scheduling uplink data, a DCI for scheduling downlink data, or a group common DCI, which is not limited in this embodiment.

[0161] Example 3:

[0162] Assume that the PCell of the NR UE and the LTE base station are deployed on the same frequency band. In order to avoid CRS interference from the LTE system, the gNB needs to avoid the REs occupied by the LTE CRS when sending the NR PDCCH. In order to ensure the flexibility of network deployment and scheduling, and reduce the PDCCH blockage on the NR PCell / PSCell, the SCell is allowed to schedule the PCell. In this embodiment, it is assumed that USS is configured on both the scheduling SCell and the scheduled PCell / PSCell. Monitoring the USS on the scheduling carrier and the scheduled carrier at the same time will cause a huge burden on the terminal side. The terminal needs to dynamically switch between the PCell / PSCell and the SCell, that is, it will only monitor the USS on the PCell / PSCell or the SCell.

[0163] In this embodiment, the network side indicates whether the terminal needs to skip the USS configured on the corresponding carrier by carrying the USS skipping indication in the DCI. The corresponding carrier is the carrier that transmits the DCI carrying the USS skipping indication. The USS skipping indication includes 1 bit of indication information.

[0164] In this embodiment, when the USS skipping indication is 0, it indicates that the terminal needs to continue monitoring the USS on the cell; when the USS skipping indication is 1, it indicates that the terminal will subsequently skip the USS on the cell. The DCI carrying the USS skipping indication can be a DCI for scheduling uplink data, a DCI for scheduling downlink data, or a group common DCI, which is not limited in this embodiment.

[0165] In this embodiment, as described above, the effective range of the USS skipping indication is a pre-configured or defined time window. When the terminal performs the corresponding USS skipping operation on the serving cell, it is only effective within the time window. Figure 3 As shown in this Figure 3 It is assumed that the time window includes the time domain monitoring positions of 3 USSs. Of course, the basic time domain unit of the time window can be a time slot, and this application does not impose any limitation.

[0166] Example 4:

[0167] The method is the same as that described in Example 2-3, except that the USS skipping indication is carried by MAC CE.

[0168] Example 5:

[0169] Assume that the NR UE's PCell and the LTE base station are deployed on the same frequency band. To avoid CRS interference from the LTE system, the gNB must avoid REs occupied by LTE CRS when transmitting the NR PDCCH. To ensure network deployment and scheduling flexibility and reduce PDCCH blockage on the NR PCell / PSCell, the SCell is allowed to schedule the PCell.

[0170] In this embodiment, it is assumed that USSs are configured on both the scheduling SCell and the scheduled PCell / PSCell. Simultaneously monitoring USSs on both the scheduling and scheduled carriers would place a significant burden on the terminal. The terminal would need to dynamically switch between the PCell / PSCell and the SCell, meaning it would only monitor USSs on the PCell / PSCell or the SCell.

[0171] In this embodiment, whether it is necessary to monitor the USS on the second carrier is determined by the USS number of the DCI sent on the first carrier. Specifically, for example, this function can be implemented by the following steps:

[0172] Step 1: Determine the first carrier by protocol pre-definition or high-level signaling (RRC signaling) indication;

[0173] The first carrier is a scheduling carrier or a scheduled carrier;

[0174] Step 2: First, monitor the PDCCH in the USS on the first carrier;

[0175] Step 3: Determine the subsequent USS monitoring behavior by monitoring the search space number corresponding to the PDCCH, including: monitoring the USS on the first carrier and the second carrier at the same time, or monitoring the USS on the first carrier only.

[0176] The correspondence between the search space number and the USS monitoring status is configured through RRC signaling.

[0177] In this embodiment, it is assumed that the first carrier is the SCell that schedules the PCell / PSCell, and the second carrier is the scheduled PCell / PSCell. As a specific example, assume that two USSs, namely USS#1 and USS#2, are configured on the SCell that schedules the PCell. The relationship between the USS ID and the USS monitoring behavior on the second carrier is configured through high-layer signaling. In this embodiment, it is assumed that USS#1 is not associated with the USS on the scheduled PCell, while USS#2 is associated with the USS on the scheduled PCell. Accordingly, when the terminal receives DCI on the USS on the SCell that schedules the PCell, if the USS number is 1, the USS will not be detected on the scheduled PCell; when the terminal receives DCI on the USS on the SCell that schedules the PCell, if the USS number is 2, the USS will not be detected on the scheduled PCell.

[0178] Example 6:

[0179] Assume that the NR UE's PCell and the LTE base station are deployed on the same frequency band. To avoid CRS interference from the LTE system, the gNB must avoid REs occupied by LTE CRS when transmitting the NR PDCCH. To ensure network deployment and scheduling flexibility and reduce PDCCH blockage on the NR PCell / PSCell, the SCell is allowed to schedule the PCell.

[0180] In this embodiment, it is assumed that USSs are configured on both the scheduling SCell and the scheduled PCell / PSCell. Simultaneously monitoring USSs on both the scheduling and scheduled carriers would place a significant burden on the terminal. The terminal would need to dynamically switch between the PCell / PSCell and the SCell, meaning it would only monitor USSs on the PCell / PSCell or the SCell.

[0181] In this embodiment, the terminal determines whether to monitor the USS on the second carrier and / or the first carrier based on the USS activation / deactivation indication information sent by the base station on the first carrier. The terminal may determine the first carrier in a predefined manner or through RRC signaling sent by the base station. In this embodiment, it is assumed that the terminal determines, through the aforementioned method, that the first carrier is the SCell that schedules the PCell, and the scheduled PCell is the second carrier.

[0182] The network side sends activation / de-activation indication signaling of the USS on the second carrier on the SCell. The indication signaling is 1-bit information carried by DCI or MAC CE, where 0 indicates not to detect the USS on the second carrier, and 1 indicates to detect the USS on the second carrier.

[0183] Before receiving activation signaling of the USS on the second carrier on the first carrier, the terminal considers that the USS on the second carrier is in an inactive state and does not monitor the USS on the second carrier.

[0184] In summary, in the embodiments of the present application, when the base station configures USS on both the scheduling carrier and the scheduled carrier, the base station dynamically indicates which carrier the terminal needs to detect USS on; when the base station configures USS on both the scheduling carrier and the scheduled carrier, the terminal determines which carrier to detect USS on through dynamic indication signaling sent by the base station. Therefore, a solution is provided for dynamically indicating USS monitoring behavior on the scheduling carrier and the scheduled carrier, which can enable flexible USS monitoring by the terminal, avoid waste of resources and energy, and improve user experience.
